Definitions

• This invention relates to the mechanism used to open and close the manhole filling ports used in bulk cargo filling in trailer/semi-trailer vehicles carrying powder and granular materials, with a remote control without human touch.
• the cover In current automatic opening manhole cover applications, the cover is opened with a pneumatic linear movement piston and a simple hinge structure. In these systems, contractions and snags occur when the lid is opened and closed. The system is difficult to open and is exposed to excessive friction. In silo trailers carrying granules and powder, the material enters the system and makes it difficult to open the system. However, since there is a mechanism on the vehicle that is not movable and closed, interference from the outside and/or insertion of foreign objects while the vehicle is driving may cause damage or breakdown of the system.
• the invention is inspired by current situations and aims to solve the above-mentioned disadvantages.
• the purpose of the present invention is to reveal the mechanism used for opening and closing the manhole filling ports used in bulk cargo filling in trailer (semi-trailer) vehicles carrying powder and granular materials, with a remote control without human touch.
• Figure 1 is the cross-sectional representation of the mechanism which is the subject of the invention.
• FIG 2 is the exploded illustration of the mechanism which is the subject of the invention.
• Figure 3 is the perspective view of the mechanism which is the subject of the invention on the trailer.
• This invention relates to the mechanism (1) used to open and close the manhole filling ports (2) used in bulk cargo filling in trailer/semi-trailer vehicles carrying powder and granular materials, with a remote control without human touch.
• ⁇ Pneumatic actuator (4) which is connected to the rotation shaft (3) with a wedge, generates air pressure and creates rotational power, moves the rotation shaft (3) thanks to the rotation power it produces, and thus enables the opening and closing of the manhole cover (2),
• connection plate (12) which is the part to which the pneumatic actuator (4) is connected, and which connects the seating channel of the bearing (10) to the manhole neck (8), contains.
• the opening and closing of the manhole cover (2) is accomplished by using the rotational power generated by the pneumatic actuator (4) air pressure. It is fixed by connecting to the connection plate (12) of the pneumatic actuator (4).
• the shaft of the pneumatic actuator (4) is connected to the rotation shaft (3) with a wedge connection and transmits the movement power.
• the rotation shaft (3) works inside the bearing (10), increasing the rotational power and reducing friction.
• the fixing plate (11) ensures that the bearing (10) works without moving in the channel it sits in.
• the rotation shaft (3) connects to the rotation plate (5) and the hinge lock plate (6) and provides the manhole cover (2) to rotate.
• the air seal (7) inflates and rests on the manhole cover (2) and provides upward movement of the manhole cover (2).
• the manhole neck (8) is the part where the hinge lock plate (6) and the air seal (7) are connected, which limits the upward movement of the manhole cover (2).
